Visualization of Distributed Parcel's Information on Mobile Device

This paper presents the use of Augmented Reality technics exploiting distributed geographical information in a mobile device using wireless network. Our system offers useful informations (number of parcel, name of the owner, agronomic structure, juridical state, and adequate plant) related to each parcel geo-referenced according to the user's position and orientation. We used inertial sensor MTi and Global Positioning System receiver to achieve user's position and orientation. Internet Communication Engine, an object-oriented middleware is used to ensure the connection between database servers and clients. To avoid eventual problem with database server, we duplicate our database on several servers and we use Icegrid service to provide load balancing between all servers.
